Detailed Description
An example of the present disclosure is explained below with reference to the drawings. In the following description, terms indicating a designated direction or position (for example, terms including "up", "down", "left" and "right") are used as necessary, but the terms are used for easy understanding of the present disclosure with reference to the drawings, and the technical scope of the present disclosure is not limited by the meanings of the terms. The following description is merely exemplary in nature and is not intended to limit the present disclosure, its applications, or uses. Further, the drawings are schematic drawings, and ratios of the respective dimensions and the like do not necessarily coincide with actual cases.
The connector 1 according to one embodiment of the present disclosure is configured to be connectable to an inspection apparatus 100 and an inspection object 200 (see fig. 3) which are an example of a connection object, and includes, as shown in fig. 1: a connector housing 10, and a first terminal connecting portion 20 swingably supported on the connector housing 10. As shown in fig. 2, the connector housing 10 is provided with an urging portion 30 inside.
As shown in fig. 1, the connector housing 10 is a box-like shape having a substantially rectangular shape as an example, and is composed of an upper housing 11 and a lower housing 12 stacked in a thickness direction (i.e., a vertical direction in fig. 1). The connector housing 10 has an opening surface 13 on one of side surfaces facing in the longitudinal direction (i.e., the first direction X), and an opening 14 having a substantially elliptical shape is provided in the opening surface 13.
As shown in fig. 3, a board 40 and a second terminal connection portion 50 connectable to the inspection apparatus 100 are provided inside the connector housing 10. The substrate 40 is electrically connected to the first terminal connection portion 20 and the second terminal connection portion 50 via connection terminals 41 (shown in fig. 6) provided at both ends of the plate surface in the first direction X. The second terminal connection portion 50 is disposed on the opposite side of the first terminal connection portion 20 with respect to the substrate 40 in the first direction X.
As shown in fig. 3, a first end 201, which is one end in a first direction X intersecting (e.g., orthogonal to) the opening surface 13, of the first terminal connecting portion 20 is positioned inside the connector housing 10, and a second end 202, which is the other end in the first direction X, is exposed to the outside of the connector housing 10 so as to be able to connect the inspection object 200. The inspection object 200 is, for example, an electronic component module having a USB connector or an HDMI connector.
As shown in fig. 4, the first terminal connecting portion 20 is disposed at a reference position P in the opening 14 with a gap 15 provided between the reference position P and the edge of the opening 14, and is supported by the connector housing 10 in a state of being swingable in any one of the vertical and horizontal directions in fig. 4 on the opening surface 13. In this embodiment, the gap 15 is provided over the entire circumference of the first terminal connecting portion 20 in the first direction X (i.e., the paper surface penetrating direction in fig. 2) at the reference position P.
Specifically, as shown in fig. 3, the first terminal connecting portion 20 includes: the connector housing 21 includes a plate-shaped pin 60 and a connector housing 21, and the connector housing 21 is provided with a first housing portion 22 extending in a first direction X, and capable of housing the pin 60 by facing a plate surface in a second direction Y (shown in fig. 4) intersecting (e.g., orthogonal to) the first direction X. In this embodiment, as shown in fig. 2, the first terminal connection portion 20 has a plurality of pins 60, a plurality of pairs of first accommodation portions 22 are provided in the connection housing 21 at intervals along the second direction Y, and the pins 60 are accommodated in the first accommodation portions 22, respectively. Thus, each pair of the first receiving portions 22 is disposed symmetrically with respect to a center line L1 of a third direction Z intersecting (e.g., orthogonal to) the first direction X and the second direction Y of the first terminal connecting portion 20 as viewed from the first direction X, and is electrically independent of each other. That is, the pins 60 accommodated in each pair of the first accommodating portions 22 are configured to be capable of holding the inspection object 200 from the third direction Z by a first contact spring portion 61 described later, and to be capable of holding the substrate 40 from the third direction Z by a second contact spring portion 62 described later.
As shown in fig. 3, a support portion 211 for supporting a biasing member (i.e., a coil spring 31) of a biasing portion 30 described later is provided at an end portion on the first end portion 201 side of the coupling case 21, and a recess 23 which is open in the first direction X and which can accommodate the inspection object 200 from the first direction X, and a confirmation window 24 are provided at an end portion on the second end portion 202 side of the coupling case 21. A first contact spring portion 61, which will be described later, of each pin 60 is disposed inside the recess 23. That is, the inspection object 200 is connected to the first terminal connecting portion 20 in the first direction X. The confirmation windows 24 communicate with the first receiving portions 22 and the outside of the connection case 21, and the first contact spring portions 61 of the pins 60 can be confirmed from the outside of the connection case 21.
As shown in fig. 5, the first terminal connecting portion 20 has a conductive shell portion 25 covering the outer surface of the connecting housing 21 and provided with a ground terminal 26 disposed inside the connector housing 10. In this embodiment, the outer shell 25 is made of metal such as iron, and covers the region of the outer surface of the connection case 21 excluding the second end 202 in a state electrically independent from the pins 60. With this configuration, when the inspection object 200 is connected to the first terminal connecting portion 20, the inspection object 200 does not contact the housing portion 25, and damage to the inspection object 200 when connected to the first terminal connecting portion 20 can be reduced. In addition, a pair of ground terminals 26 are provided at both ends of the housing portion 25 in the second direction Y, respectively.
As shown in fig. 3, a recess 212 capable of accommodating the housing portion 25 is provided on the outer surface of the connection housing 21. The recess 212 is configured such that the outer surface of the housed case portion 25 and the outer surface of a portion where the recess 212 of the connection case 21 is not provided (for example, the end 213 on the second end 201 side of the connection case 21) are on the same plane.
As shown in fig. 6, each pair of ground terminals 26 is arranged to face each other in the third direction Z, and is configured to be in contact with the connection terminal 41 of the substrate 40 in a state of being elastically deformed in the third direction Z.
As shown in fig. 2, the biasing portion 30 is disposed inside the connector housing 10, and biases the first terminal connecting portion 20 toward the reference position P with respect to the connector housing 10. Specifically, the biasing portion 30 is configured by a plurality of biasing members (four coil springs 31 in this embodiment), and the four coil springs 31 are arranged symmetrically with respect to a virtual straight line (for example, a center line L1 in the third direction Z of the first terminal connecting portion 20) orthogonal to the first direction X.
Each coil spring 31 is housed in a coil spring housing portion 16, and the coil spring housing portion 16 is configured by a substantially cylindrical recess portion 214 provided in the support portion 211 of the coupling case 21, and substantially cylindrical recess portions 111 and 121 provided in the respective cases of the upper case 11 and the lower case 12 and disposed so as to face the recess portion 214 of the coupling case 21. By using the coil spring 31 as the urging member, the first terminal connecting portion 20 can be swung in the first direction X in addition to an arbitrary direction on the opening surface 13.
As shown in fig. 7, each pin 60 has a plate shape and includes: the first contact spring portion 61 and the second contact spring portion 62, and the intermediate portion 63 and the buffer spring portion 64 that are arranged in series in the first direction X between the first contact spring portion 61 and the second contact spring portion 62. That is, the first contact spring portion 61, the intermediate portion 63, the buffer spring portion 64, and the second contact spring portion 62 are aligned in the first direction X. The pins 60 are formed by, for example, electroforming, and integrally constitute the first contact spring portion 61, the intermediate portion 63, the buffer spring portion 64, and the second contact spring portion 62.
Each of the first contact spring portion 61 and the second contact spring portion 62 has a curved shape as viewed in the second direction Y, and is configured to be elastically deformable in the third direction Z with respect to the intermediate portion 63. The first contact spring portion 61 is formed of a plurality of band-shaped elastic pieces (two band-shaped elastic pieces 611 and 612 in this embodiment).
The intermediate portion 63 has a substantially rectangular shape, and both ends in the first direction X are connected to the first contact spring portion 61 and the buffer spring portion 64, respectively. A first positioning portion 631 is provided at an end of the intermediate portion 63 on the buffer spring portion 64 side, and the first positioning portion 631 regulates the movement of the pin 60 in the first direction X and in the direction of the second contact spring portion 62 when the pin is accommodated in the first accommodation portion 22 of the connection housing 21. The first positioning portion 631 is constituted by a flat surface extending in the third direction Z in a direction away from the damper spring portion 64.
The buffer spring portion 64 has a substantially rectangular frame shape protruding from the intermediate portion 63 in the third direction Z, and is configured such that both end portions in the first direction X are connected to the intermediate portion 63 and the second contact spring portion 62, respectively, and are elastically deformable in the second direction Y (i.e., the plate thickness direction) with respect to the intermediate portion 63. A second positioning portion 641 is provided at an end portion of the buffer spring portion 64 on the side of the intermediate portion 63, and this second positioning portion 641 restricts the movement of the pin 60 in the first direction X and in the direction of the first contact spring portion 61 when it is stored in the first storage portion 22 of the connection housing 21. The second positioning portion 641 is constituted by a flat surface extending in the third direction Z in a direction away from the damper spring portion 64 and in a direction opposite to the first positioning portion 631 of the intermediate portion 63.
Further, a protrusion 642 extending from the second positioning portion 641 toward the first contact spring portion 62 along the first direction X is provided at one end portion of the second positioning portion 641 distant from the intermediate portion 63 in the third direction Z. As shown in fig. 3, the projection 642 is provided in the third direction Z on the support portion 211 of the coupling case 21 and is accommodated in the recess 215 disposed between the coil spring 31 and the intermediate portion 63.
As shown in fig. 3, the second contact spring portion 62 and the buffer spring portion 64 are located outside the connection housing 21 and inside the connector housing 10, respectively. The buffer spring portion 64 is housed in the second housing portion 17 provided inside the connector housing 10, and the second contact spring portion 62 is housed in the third housing portion 18 provided inside the connector housing 10.
As shown in fig. 8, the shortest distance D1 between the plate surface of the intermediate portion 63 in the second direction Y and the first housing portion 22 is smaller than the shortest distance D2 between the plate surface of the damper spring portion 64 in the second direction Y and the second housing portion 17. The thickness W1 of each stitch 60 is set to be 1/2 or less (preferably 1/3 or less) of the shortest distance W2 between the plate surfaces of the adjacent stitches 60. Although not shown, the shortest distance between the plate surface of the second contact spring portion 62 and the third housing portion 18 in the second direction Y is substantially the same as the shortest distance D1 between the plate surface of the intermediate portion 63 and the first housing portion 22 in the second direction Y.
The connector 1 has: a connector housing 10 having an opening surface 13 provided with an opening 14; a first terminal connecting portion 20 disposed at a reference position P in the opening 14 with a gap 15 provided between the first terminal connecting portion and an edge of the opening 14, and supported by the connector housing 10 in a state of being swingable on the opening surface 13; and a biasing portion 30 for biasing the first terminal connecting portion 20 toward the reference position P. With the above configuration, even when the connection object such as the inspection object 200 is connected from a direction corresponding to the direction intersecting the connection direction of the first terminal connecting portion 20 (i.e., the first direction X), the first terminal connecting portion 20 can be returned to the reference position P by the biasing force of the biasing portion 30 after the first terminal connecting portion 20 is temporarily displaced from the reference position P in opposition to the biasing force of the biasing portion 30. Therefore, the first terminal connecting portion 20 can be self-aligned with the connection object such as the inspection object 200, and therefore, the connector 1 can be connected without damaging the connection object such as the inspection object 200.
The first terminal connecting portion 20 has a conductive shell portion 25 covering the outer surface thereof and provided with a ground terminal 26 disposed inside the connector housing 10. The loss of the signal in the high frequency region flowing through the connector can be reduced by this housing portion 25.
Further, a substrate 40 electrically connected to the first terminal connecting portion 20 is provided inside the connector housing 10, and the ground terminal 26 is configured to be in contact with a connection terminal 41 of the substrate 40 in an elastically deformed state. With the above configuration, the contact pressure between the ground terminal 26 and the connection terminal 41 of the substrate 40 can be increased, and the contact reliability between the ground terminal 26 and the connection terminal 41 can be improved.
The biasing portion 30 is formed of a plurality of biasing members (e.g., coil springs 31), and the plurality of biasing members are arranged symmetrically with respect to a virtual straight line L1 orthogonal to the first direction X. With the above configuration, the difference in the biasing force with respect to the first terminal connecting portion 20 can be reduced, and the first terminal connecting portion 20 can be more reliably swung as designed. As a result, the first terminal connecting portion 20 can be more reliably self-aligned with the connection object such as the inspection object 200.
In addition, the first terminal connecting portion 20 includes: a plate-shaped pin 60 and a connection housing 21 provided with a first housing portion 22 extending in the first direction X such that plate surfaces thereof face each other in the second direction Y and housing the pin 60, wherein the pin 60 includes: the first contact spring portion 61 and the second contact spring portion 62, and the intermediate portion 63 and the buffer spring portion 64 that are arranged in series in the first direction X between the first contact spring portion 61 and the second contact spring portion 62. The first contact spring portion 61 and the second contact spring portion 62 are configured to be elastically deformable in the third direction Z with respect to the intermediate portion 63, both end portions of the intermediate portion 63 in the first direction X are connected to the first contact spring portion 61 and the buffer spring portion 64, respectively, and the buffer spring portion 64 is configured to be elastically deformable in the second direction Y with respect to the intermediate portion 63 while both end portions of the first direction X are connected to the intermediate portion 63 and the second contact spring portion 62, respectively. The second contact spring portion 62 and the buffer spring portion 64 are located outside the connection housing 21 and inside the connector housing 10, and the connector housing 10 is provided with a second receiving portion 17 that extends in the first direction X and that can receive the buffer spring portion 64. The shortest distance D1 between the plate surface of the intermediate portion 63 in the second direction Y and the first housing portion 22 is smaller than the shortest distance D2 between the plate surface of the damper spring portion 64 in the second direction Y and the second housing portion 17. With the above configuration, even if a stress in a direction (for example, the second direction Y) intersecting a predetermined contact direction is applied to the pins 60, the stress can be dispersed by the buffer spring portions 64, and damage to the pins 60 can be reduced, since the connection object such as the inspection object 200 is connected to the first terminal connection portions 20 from a direction intersecting the contact direction (that is, the first direction X). That is, even when the connection object such as the inspection object 200 is connected to the first terminal connection portion 20 from a direction intersecting the contact direction, the pin 60 which is less likely to be damaged can be realized.
The connection housing 21 has a confirmation window 24 that communicates with the first housing portion 22 and the outside of the connection housing 21 and allows the first contact spring portion 61 to be confirmed from the outside of the connection housing 21. The confirmation window 24 allows the user to easily confirm the received state of the first contact spring 62 of the pin 60 received in the first receiving portion 22.
In addition, the first terminal connecting portion 20 includes: the plurality of stitches 60 and the plurality of first receiving portions 22 that are arranged at intervals in the second direction Y and that respectively receive the stitches 60 are provided, and the plate thickness W1 of each stitch 60 is 1/2 or less of the shortest distance W2 between the plate surfaces of the adjacent stitches 60. With the above configuration, the insulation of each pin 60 can be reliably ensured.
The pin 60 further includes positioning portions 631 and 641, and the positioning portions 631 and 641 are provided between the first contact spring portion 61 and the second contact spring portion 62 and position the first direction X with respect to the first terminal connecting portion 20 when the first housing portion 22 is housed. The positioning portions 631 and 641 reduce the pins 60 from falling off from the first receiving portion 22.
In addition, the positioning part has: a first positioning portion 631 provided on one side of the intermediate portion 63 in the third direction Z and restricting movement to one side of the first direction X (for example, in the direction of the second contact spring portion 62), and a second positioning portion 641 provided on the other side of the buffer spring portion 64 in the third direction Z and restricting movement to the other side of the first direction X (for example, in the direction of the second contact spring portion 61). With the above configuration, the stitches 60 can be further reduced from falling off from the first housing portion 22.
In the connector 1, the connector housing 10 is formed by laminating the upper housing 11 and the lower housing 12 in the third direction Z, but is not limited thereto. For example, as shown in fig. 9, the left case 71 and the right case 72 may be laminated in the second direction Y. In this case, as shown in fig. 10, the four coil springs 31 of the biasing portion 30 may be arranged symmetrically with respect to a center line L2 of the first terminal connecting portion 20 in the second direction Y, as viewed from the first direction X (i.e., the paper surface penetrating direction of fig. 10).
Further, although the shortest distance D1 between the plate surface of the intermediate portion 63 of the pin 60 housed in the first housing portion 22 and the first housing portion 22 is configured to be smaller than the shortest distance D2 between the plate surface of the buffer spring portion 64 of the pin 60 and the second housing portion 17, the present invention is not limited thereto, and the shortest distance D1 may be configured to be the same as the shortest distance D2, for example.
The outer shell 25 is not limited to a case of being configured to cover a part of the connection housing 21, and may be configured to cover the entire connection housing 21 as shown in fig. 9, for example, and the outer shell 25 may be omitted when it is not necessary to consider a loss of a signal in a high frequency region.
The ground terminal 26 is not limited to the case of being configured to be in contact with the connection terminal 41 of the substrate 40 in a state of being elastically deformed, and may be configured to be in contact with the connection terminal 41 of the substrate 40 in a state of not being elastically deformed. In this case, for example, the ground terminal 26 may be connected to the connection terminal 41 of the substrate 40 by soldering or the like to improve contact reliability.
The biasing portion 30 is not limited to being configured by four coil springs 31, and may be configured by one to three coil springs 31, or may be configured by five or more coil springs 31, for example. The biasing portion 30 is not limited to the case where the plurality of coil springs 31 are disposed vertically in the third direction Z, and may be disposed vertically in the third direction Z or disposed horizontally in one or both of the second direction Y and the plurality of coil springs 31.
The biasing member is not limited to the coil spring 31, and may be formed of a plate spring 32, for example, as shown in fig. 12. In fig. 12, two leaf springs 32 are disposed respectively above and below the third direction Z (only three leaf springs 32 are shown in fig. 12), and two leaf springs 32 are disposed respectively on both the left and right sides in the second direction Y.
The terminal connecting portion may be appropriately changed in structure according to the design of the connector 1 and the like.
For example, the pin of the first terminal connecting portion 20 is not limited to the pin 60, and other configurations of pins may be used. For example, a pin formed by a method other than electroforming may be used as the pin of the first terminal connection portion 20, or a pin not provided with the positioning portions 631 and 641 may be used.

According to the connector 1 of the fourth aspect, the difference in the urging force with respect to the terminal connecting portion 20 can be reduced, and the terminal connecting portion 20 can be swung more reliably in accordance with the design. As a result, the terminal connecting portion 20 can be more reliably self-aligned with the connection object such as the inspection object 200.
A connector 1 according to a fifth aspect of the present disclosure is,
the terminal connecting portion 20 includes:
a plate-shaped pin 60;
a connection housing 21 provided with a first housing portion 22, the first housing portion 22 extending in the first direction X and being opposed to a plate surface in a second direction Y intersecting the first direction X to house the pin 60;
the pin 60 has:
a first contact spring portion 61 and a second contact spring portion 62;
an intermediate portion 63 and a buffer spring portion 64 arranged in series in the first direction X between the first contact spring portion 61 and the second contact spring portion 62;

the connector housing 10 is provided with a second receiving portion 17 extending in the first direction X and receiving the buffer spring portion 64,
a shortest distance D1 between the plate surface of the intermediate portion 63 and the first housing portion 22 in the second direction Y is smaller than a shortest distance D2 between the plate surface of the damper spring portion 64 and the second housing portion 17 in the second direction Y.
According to the connector 1 of the fifth aspect, even if a connection object such as the inspection object 200 is connected to the terminal connection portion 20 from a direction intersecting the contact direction (i.e., the first direction X), and a stress in a direction intersecting the contact direction (e.g., the second direction Y) is applied to the pins 60, the stress can be dispersed by the buffer spring portions 64, and damage to the pins 60 can be reduced. That is, even when a connection object such as the inspection object 200 is connected to the terminal connection portion 20 from a direction intersecting the contact direction, the pin 60 which is less likely to be damaged can be realized.
